I found this really interesting but it happened so quick that I couldnt get a good look at it. Anyway im going to try and develop some thoughts on this:
Firstly..were the UV lights installed so that this map could be drawn and concealed? [very "Da vinci code" aint it!]..or did the UV lights have another purose? At the moment it would seem to me as if the UV lights were installed for this very function..but then wouldnt that mean that they [Dharma?] planned to hide important information from prying eyes? Hmm
EDIT/UPDATED
Here's a larger view of the >>>>>
Map<<<<<
Okay, so theres a hatch which appears to have been crossed out..now does this mean that there are or were 7 hatches!? ..or did the artist just draw one of the hatches in the wrong location? ..Hmm, well im starting to think that there might be a
7th, 'secret' hatch!..
